BARREL- HEATER.

SPECIFICATION forming part of Letters Patent No. 745,432, dated December1, 1903.

Application filed April 4, 1903. Serial No. 151,167. (lilo model.)

To 0.0% whom it may concern:

Be it known that I, ALFORD ALVIN Gornv, a citizen of the United States,residing at Gladerun, in the county of Vfarren and State ofPennsylvania, have invented a new and useful Barrel-Heater, of which thefollowing is a specification.

This invention is an improved barrel-heating device, the object being toprovide a simple and highly-efficient construction of barrel-heaterwhich is so constructed that in opera-ting the same it will not benecessary to lift the barrels over the burner when placing or removingthe barrels.

Another object of the invention is to pro.- vide a heater using gas andone which will automatically operate to out the gas off and on asrequired, thereby economizing in the use of the gas, inasmuch as it isonly consumed to any considerable extent when the barrel is beingheated.

A still further object is to provide a barrelheater in which theoperation of asingle lever will be sufficient to effect the operation ofall the other various parts of the apparatus.

With these objects in view my invention consists, essentially, in theemployment of a bed-plate having an opening in the bottom thereof, aburner located beneath the bedplate and adapted to be projected throughthe opening therein, a case arranged beneath thebed-plate and in whichthe swinging burner moves, an igniter arranged in connec-' tion with thesaid case by means of which the burner is lighted as it passes upwardlythrough the opening in the bed-plate, a hood arranged upon the bed-plateand within which the barrel to be heated is placed, said hood having adoor at the forward side thereof, 7 together with means for raising andlowering of a barrel-heater constructed in accordance with my invention.Fig. 2 is a vertical sectional view of the heater, the door-operatingmechanism being omitted. Fig. 3 is a horiing A adjacent the elongatedopening A zontal sectional view on the line 3 3 of Fig.2. I Fig. 4. is adetail sectionalview taken through a port-ion of the upper end of thehood. Fig. 5 is a detail View, partly in plan and partly in section,showing the manner of arranging the doors at the front of the hood andjacket. Fig. 6 is a detail plan View, partly in section, showingthemanner of arranging the burner and pipe, the igniter, and the mannerof connecting the burner and igniter pipes to the gas-supply pipe andalso the case for containing the burner when not in operation. Fig. 7 isa detail perspective view showing the arrangement of the valves forcontrolling the gas-supply. Figs. 8 and 9 are detail sectional views ofthe igniter and burner valves, respectively. FigqlO is a detail viewillustrating the sliding plate through which the burner-pipe passes andwhich closes the rear end of the case for the said burner.

In constructing a barrel-heater in accordance with my invention I employa bed-plate A, which has an elongated opening A produced therein andalso a small circular open- A hoodB is arranged upon the bed-plate andis of such size that the barrel to be heated can be conveniently locatedtherein, and when the barrel is arranged within the hood and rests uponthe bed-plate it will en compass the openings A and A as most clearlyshown in Fig. 2, and it will of course be understood that at the timethe barrel is heated it is open at one or both ends. The hood B is openat the front and'is provided with a verticallysliding door 13, said doorsliding between the upright guiding-standards Biwhich are connected tothe forward corners of the hood and extendaconsiderabledistanceabovethesame. If desired, a jacket 0 may be arranged within thehood depending from the top thereof, and when such jacket is employed inconnection with the hood it also is provided with an upwardly-slidingdoor 0, suitable guidingstandards being arranged adjacent andin'parallel relation to the standards 13*, and the sliding bars B andC'are connected by means of a strip 0 which 7 eifectively. closes thehood when the doors are lowered, said stripbeing of sufficient width toengage the top of the hood, as most clearly shown in Figs. 2 and 5.

This strip also forms the connecting means between the doors B and C, sothat when one door is raised the other door will raise also and likewisewhen lowering.

The doors are raised by means of a cable D, which passes over a pulleyD, journaled in a bracket D arranged upon the cross-piece D connectingthe guiding-standards, and the other end of the cable is connected tothe lever E, pivoted between the upright rods E, which are connected tothe bed-plate at the rear of the hood, and the rear end of the lever ispivotally connected to a link-rod F, the lower end of which is connectedto a crank-arm G, carried by a rock-shaft H, which. is journaled inbearings H, connected to the bed-plate. An-

other crank-arm I is mounted upon the end of the rock-shaft H, saidcrank-arm having a pull-lever K connected thereto, said lever restingupon a pin K and projecting upwardly and forwardly within convenientreach of the operator, the forward end being shaped into a suitablehandle .or grip K By pushing down on the lever K the rock-shaft H isturned, throwing the crank-arm G upwardly, which movement forces theforward end of the lever downwardly, thereby pulling upon the cable Dand raising the doors 1% and O.

The lever E is provided with a weight E to assist in this operation,said weight being adjustable. Vhen the doors are raised, the barrel tobe heated is placed within the hood, and by reversing the movement ofthe rod or lever K the doors are closed.

A socket L is rigidly connected to the rockshaft H and in which isfitted the burner-pipe M, said pipe having an elbow-joint M, and aburner hi is arranged at the extreme end of the pipe. The pipe is ofsuch length that the upwardly-extending end carrying the burner can beprojected through the elongated opening A up into the barrel when thedoors of the hood and jacket have been closed,and by connecting theburner-pipe to the rockshaft H these movements are made simultaneouslywith the operation of said doors.

N indicates a gaspipe, which is bent at N to permit the movement of theburner-pipe, and the said burner-pipe and gas-pipe are connected bymeans of a flexible pipe 0, which leads from a valve 0, arranged uponthe gaspipe and operated by means of an arm 0 to which is connected alink 0 which link in turn is connected to an angular lever O, rigidlymounted upon the rock-shaft H, so that when said rock-shaft is operatedfor the purpose of closing the doors and raising the burner the valve 0,controlling the supply of gas to the burner-pipe, will be opened andwill be closed when the reverse operations take place. A casing P isarranged directly beneath the bed-plate and is made, essentially,V-shaped for the purpose of accommodating the burner and pipe when theyare withdrawn from the barrel and hood. This casing is closed on allsides in order to prevent air pass ing upwardly into the heater, and atthe rear end, where the burner-pipe passes through, I provide a slidingplate P, having an opening P through which the burner-pipe passes, andthis plate slides in guides P formed upon the casing, and-the plate isof such length that it will ettectively close the rear end of the easingwhen the burner is in either a raised or lowered position. .A smallair-inlet P regulated by a damper, is made in one side of the casing. Anigniter-pipe Q has its forward end projected into the casing, projectedbe low the elongated opening Ain the bed-plate and in close proximity tothe path of the burner in its upward flight, the purpose of said igniterbeing to supply the necessary light for lighting the burner as it ismoved upwardly into the barrel and hood.

The igniter-pipe Q is connected to the valve Q, which is incommunication with the gassupply pipe N and is operated by an arm Q link(23, and angle-lever Q said angle-lever being rigidly connected to therock-shaft H. The valves Q and O are so constructed with reference toeach other that when the shaft H is rocked one valve will be open andthe other closed, according to the movement of the said rock-shaft, andwhen the burner is in its lower position, as shownin dotted lines inFig. 2, the valve 0 is closed and the valve Q open, so that the igniteris burning and the burner extinguished. As the burner moves upwardly,however, the valve 0 opens, gas is supplied to the burner, and inpassing close to the ig- I niter the burner becomes lighted and passesupwardly into the hood in the lighted condition, and the igniterwalve Qis then closed and is not opened again until the burner descends. Bymeans of this construction the use of gas is economized, as noconsiderable quantity of gas is consumed except when the burner is inoperation and used for heating the barrels.

An opening A is produced in the top of the hood adjacent the center, andthe sliding dam per A is adjustable over said opening for the purpose ofregulating the escape of gas and products of combustion. Additionalopenings A are produced in the top of the hood.

adjacent the edges and through which the gas and products of combustioncan escape when the damper A is closed. The jacket 0 within the hood isnot essential and may be dispensed with, if so desired. openings Madjacent the rear ends to permit air to enter for the purpose ofproducing more perfect combustion and a greater heat.

In operation the doors are raised by pushing upon the rod or lever K,and simultaneous with this operation is the lowering of the burner. Thebarrel is then placed upon the bed-plate over the openings, and bypulling upon the rod the doors are closed and the burner projectedupwardly into the barrel to be heated, and as the said burner passes theigniter it will be lighted, as heretofore described. All of the minoroperations of my invention The burner-pipe N has have been fullydescribed, and further description is not deemed necessary.
